Baby Rock Urchin?

Just found this tiny little guy while feeding the tank. All I can figure is my pair of Rock Urchins have had a visit from the Aquastork. Anyone else agree? He's about 2mm diameter.

 

Not an urchin. Some kind of a polyp/anemone. He's attached to a snail, which is why I thought he was moving.

 

Looks like a ball anemone.

 

Thanks for the input. On further research and a closer look, I think I agree. There are some accounts of them getting to be a problem. Remove, leave it alone, other thoughts?

 

Most say to leave them alone, but they will irritate some corals. I have several (started with a couple) that I would prefer to get rid of. I did manage to get them to move out of my zoas and into dark spots under rocks where there aren't corals, so that was good enough for me LOL.

 

You got them to move? Played really loud music for a couple weeks and offered to hire a nem moving service? I keed!

How!? Just careful picking and replacement?

 

Sorry, missed your question till now.
I injected mine in the mouth with lemon juice. They didn't like that, so they moved LOL.
